I would recommend you get the Hardened edition, the Night-vision goggles may be cool but they're essentially useless and eventually will get in the way. Best save your money for other games or whatever...

You also may want to save your money for all the other stuff that is coming out. They have a custom MadKatz controller with two extra buttons that can be mapped to any other button you want, console skins, controller skins, a throat mic, and one other thing I think.
